CARBURETER.

SPECIFICATION forming part of Letters Patent N 0. 709,866, datedSeptember 30, 1902.

Application filed March 29,1901. Renewed August 26, 1902. Serial No.121,095. (No model.)

To all whom it may concern. I

Be it known that I, EDOUARD BOUCHAUD- PRACEIQ, a citizen of the Republicof France, residing in Angouleme, Oharente, France, have inventedcertain new and useful Improvements in Oarbureters, of which thefollowing is a specification. I

This application for patent relates to a portable carbureting-receptacleincapable of explosion for containing a hydrocarbon, which is held inposition by an absorbent material and yet is pervious to air. Thisreceptacle is provided along its axis with a very long cock, the casingof which has a helicoidal opening of suitable width, while the plug isin the form of an inner tube and is provided with a rectilinear openingarranged along one of its generating-lines. The crossing or coincidenceof these two openings determines the orifice for the entrace ofcarbureted air to the interior of the tubular plug, which also servesfor the exit of the gas and is connected to the supply-pipe. It will beunderstood that according to the position of the plug relatively to itscasing the passage produced by the crossing of the two openings(rectilinear and helicoidal) will be more or less removed from thebottom of the receptacle, and consequently the air to be carbureted willpass through a more or less thick layer of material. By this means therichness of the mixture can be determined with the greatest ease.Similarly by the mere inspection of the angle formed by the plug of thecock with the initial position the degree of exhaustion of thereceptacle can be ascertained. A scale of hundredths provided on one ofthe ends of the receptacle and over which moves a pointer carried by theplug gives this latter indication by simply reading off the same. On theother hand, the gas-supply orifice in descending assumes varyingpositions and describes a circle in horizontal projection. The result ofthis is that the contents of the receptacle are drawn off in a rationaland systematic manner. The admission of the air to be carbureted isefiected by means of a crown or ring pierced with horizontal holes,which direct the air horizontally over the the same in order to becarbureted.

The accompanying drawings illustrate my carbureting-receptacle invertical section in Figure 1 and in plan in Fig. 2. Figs. 3 and 4 arerespectively a part elevation and a horizontal section of thecock. Fig.5 shows the lower part of the cock with the plug in another position.Fig. 6 illustrates by way of example an arrangement for illuminatingwith incandescent burners.

The receptacle a, containing the absorbent and pervious material 17, isprovided at one end with a union 0, on which is attached the union (1,that is formed with a side passage 'm for allowing admission of theouter air. A ring having horizontal holes 6 distributes the air over thematerial I). The cock is composed of a tubular casing f, attached at itsupper part to the union 0. It is surrounded with wire-gauze g. A slot oropening h is formed in the wall and has the shape of a helix of one turnless its own width in such a manner that when the cock is opened at thetop it is closed at the bottom, and conversely. The plug 1' works withslight friction in the tube f and is formed with a straight slot j alongone of its generating-lines. This plug serves for the exit of carburetedair which passes out through the upper part ofi said plug. It will beunderstood that by reason of this arrangement the 'carbureted air whichhas passed through the absorbent material I) can only pass out throughthe orifice produced by the crossing of the two slots. This orifice willbe situated at a greater or less height, according to the position ofthe rotating plug 2' relatively to the tubular casing. Likewise everyposition of the plug will correspond to a different position of theorifice. A pointer it, carried by the plug 1', indicates on a dial Z,which is divided into hundredths, the position of the plug relatively tothe casing, and consequently the height of the outlet-orifice of thecock. By this means the degree of exhaustion of the receptacle can beascertained. The air entering through the side passage 'm passes downthe union d through the union 0 and then through the holes 6, whence itis distributed horizontally over the pervious material I). The air thenpasses through the said material to the level of the supply-orifice,which it reaches by a horizontal path.

the helicoidal opening determines the level of the orifice, whereby saidlevel can be varied by the turning of one tube relatively to the 15other.

In witness whereof I have hereunto signed my name in the presence of twosubscribing Having thus described the nature of this invention and thebest means I know of carrying the same into practical effect, I claim Acarbureler comprising a receptacle completely filled with porousmaterial adapted to retain hydrocarbons and which is pervious to thepassage of air to form a combustible mixwitnesses.
